Flowers and Tears Mark Chernobyl Anniversary

Mourners laid red carnations -- symbols of grief -- in the shadow of the ruined Chernobyl power station on Wednesday as they marked the 20th anniversary of the world's worst civil nuclear accident.

Hundreds filed past a memorial wall engraved with the names of the local fire crew. They were among the first to perish when Chernobyl's reactor No. 4 blew up on April 26, 1986, spewing radioactive dust across Europe.
